Answer 1

You can use the Where method to filter out the upper case characters, and the Char.IsUpper method can be used as a delegate directly without a lambda expression. You can create the resulting string from an array of characters:

string abbreviation = new String(enumTypeName.Where(Char.IsUpper).ToArray());
